...on the driver's side. I've purchased the new upstream sensor and I've been lucky enough to get the sensor tool on the sensor, but there is no way I can get the ratchet on the tool, much less get my arm up in there (from the bottom) far enough to get the job done...and I can't get to it from the top either.

Anybody done this on the XJ8...how'd you do it?

 

Take a look at the thread,
V8 O2 sensor changing tips? and the technique described by Icebreaker.
I used a 22 mm crows foot to remove the sensor though a short collar 02 socket SP tools 88750 may have done the job. Found it in the toolbox afterwards! I got it from the Volvo IPD site.
Not difficult, but time consuming.

Ah yes, I see it now. Thanx for pointing that out to me Dan.

I could see that I wanted to remove the heat shield, but I was trying to do so without moving the coolant tank. I guess now I will go back (when it stops raining) at it with a new attitude and determination...and a better plan.

Thanx again Dan.

 

Thanx to you as well Quad.

 

Are you sure you need a new O2 sensor. My bad O2 sensor code turned out to be a MAFS that needed cleaning. I must say it is a VERY tight spot to get to the O2 sensor.
Good luck.
